Problem Description:
The task involves solving a series of 1-digit by 1-digit multiplication problems. Each problem is presented in the format \( a \times b \), where \( a \) and \( b \) are single-digit numbers.
Solution Approach:
We will solve each multiplication problem step by step. The general formula for multiplication is:
\[
a \times b = \text{product}
\]
We will compute the product for each pair of numbers.
Step-by-Step Solution:
#### First Row:
1. \( 3 \times 5 = 15 \)
2. \( 6 \times 2 = 12 \)
3. \( 2 \times 4 = 8 \)
4. \( 5 \times 9 = 45 \)
5. \( 1 \times 8 = 8 \)
6. \( 7 \times 2 = 14 \)
#### Second Row:
1. \( 8 \times 1 = 8 \)
2. \( 0 \times 7 = 0 \)
3. \( 5 \times 3 = 15 \)
4. \( 4 \times 9 = 36 \)
5. \( 5 \times 0 = 0 \)
6. \( 9 \times 6 = 54 \)
#### Third Row:
1. \( 2 \times 2 = 4 \)
2. \( 4 \times 6 = 24 \)
3. \( 2 \times 0 = 0 \)
4. \( 5 \times 7 = 35 \)
5. \( 8 \times 5 = 40 \)
6. \( 6 \times 3 = 18 \)
#### Fourth Row:
1. \( 3 \times 5 = 15 \)
2. \( 5 \times 4 = 20 \)
3. \( 1 \times 8 = 8 \)
4. \( 9 \times 1 = 9 \)
5. \( 0 \times 5 = 0 \)
6. \( 7 \times 9 = 63 \)
Final Answers:
Combining all the results, we have:
\[
\begin{array}{cccccc}
15 & 12 & 8 & 45 & 8 & 14 \\
8 & 0 & 15 & 36 & 0 & 54 \\
4 & 24 & 0 & 35 & 40 & 18 \\
15 & 20 & 8 & 9 & 0 & 63 \\
\end{array}
\]
Boxed Final Answer:
\[
\boxed{
\begin{array}{cccccc}
15 & 12 & 8 & 45 & 8 & 14 \\
8 & 0 & 15 & 36 & 0 & 54 \\
4 & 24 & 0 & 35 & 40 & 18 \\
15 & 20 & 8 & 9 & 0 & 63 \\
\end{array}
}
\]
